What to Compare Before Buying
- Reach: Check whether the chain can go around the bicycle and reach the intended anchor. Confirm the usable chain length for this exact lock before choosing it.
- Pass-through clearance: Compare the stated 1.25 in male-end diameter with the openings on the bicycle and anchor point.
- Combination setup: The initial code is stated as 00000. Consult the product instructions for setting and using a personal code, and make a plan to remember it.
- Security expectations: No test rating or measured security performance is provided. Do not treat general resistance descriptions as a guarantee against theft.
Compatibility, Size and Fit
The lock is described for bicycles, e-bikes and scooters, along with gates, fences and other items. Fit depends on the chain’s usable reach and whether its end can pass through the gaps in your setup. Check the specific frame, wheel and anchor arrangement rather than assuming it will fit every bicycle.
What Is Included
The listed quantity is one lock, with a polypropylene fabric sleeve covering the chain. No separate mounting bracket or other accessory is specified.
Plan Your Locking Setup
Before relying on the lock, identify the anchor point and route the chain would need to take. Check both the reach and the tightest pass-through gap, then set a personal combination according to the product instructions. These checks help establish whether the lock fits your intended arrangement; they do not establish a level of theft protection.
Before You Decide
Confirm the usable chain reach and the 1.25 in end clearance for your intended setup. Consider whether a five-digit combination is suitable for you, and treat security descriptions as unverified claims rather than a test rating.
